The highly reflective surface of the polished porcelain tiles adds depth and dimension to a room. Because they are manufactured mainly in larger sizes, their application is suited to larger floor areas. Durability compares with the strength of natural granite. Polished porcelain tiles are available mostly in neutral tones. They add a striking complement to more modern, uncluttered interiors, sometimes interspersed with either matt or shiny mosaics, an elegant border or an elaborately contrasting rossone.
